This invention relates to conveyor chutes. It is among the objects ofthe present in: vention to provide a novel and improved chute for thedischarge of material from a bin or the like. i

A further object of the present invention is to provide a novel andimproved covered chute whereby material falling into the chute willenter from the sides thereof.

A further object of the present invention isto' provide a covered chutewhereby material passing into the chute will not be subject to thepressure of material lying thereover.

A further object of the present invention is to provide a novel andimproved covered chute, the cover being spaced from the sides of thechute to prevent entrance of material between the cover and the chuteand to prevent pressure of material overlying the chute from restrictingthe passage of material therethrough.

Other important objects olithe present invention include the combinationand interrelation of parts whereby the whole forms a novel, simple andimproved structure well designed to meet the demands of economicmanufacture.

Other objects and features of the present invention will be apparentfrom a consideration of the following specification taken in conjunctionwith the accompanying drawings, in which Figure l is a vertical sectionthrough a ma- V terial bin provided with the present invention, thechute of the present invention being shown partially in section, and

Fig. 2 is a sectional view taken on lines 2-2 of Fig. 1.

Referring more particularly to the drawings, the invention is shown inconjunction with a conventional coal bin. It will readily be seen,however, that the invention is applicable to various types of materialbins. It

confined to the specific rectangular chute construction herein shown andthat the device is readily applicable to other forms of chutes, such asthe V type chute or the spiral chute. By the present invention thematerial'in which is under the 1 prevents downwardvertical pressure ofthe material from interfering with' the dis- -chargeofthematerialthrough the chute. It

r will furtherbe seen that the invention is not the chute is protectedfromthc. weight of material overlying the chute, thus readyidis chargetroin thechute ls'iprovided regardless the amount of inaterialin thebin.

Befcrring specifically to that formof the invention shown in thedrawing, therbin is generally indicated by the numeral 10,.the

material therein beingindicated by the nu- =meral 11. Extendingtransversely of thebin in the usual tashion,.a chute 12 is providechyfiowhich is gener llyU-shapcd in. cross section I as indicated in Fig. 2. The chute extends to the bottom of the bin 10 where it registers with "adischarge aperture 13, which may be suitably closedbby any convenienttype 01 435 door,as illustrated' byaslidingdoor 14-. It will beunderstood that the chute 197: may be of=any desired cross-section andthat its :po-

sition =withinthe bin forms no part. of the present invention, theinvention being ap-:=?0'

plicable to-many ditlerent varieties of bins and chutes.

For preventing *the lower portion; of -the' 1 chute from being blockedby the p ressure of material overlying at, a cover 15 1sprov1ded for thechute andissupported. there-over in spaced relation by suitable'U-xshaped bracket members lG-to which the cover 15 is secured by sutable bolts or liven-nae indlcatedat 17, the brackets being secured tothe sides or tea the chute 12 by suitable securing means 18'.

As indicatedinili ly-it will be seenthat throughoutthe {entire length ofthe chute 'erial 11, the cover 15 will be readily understood that theanateral is free to enter the chute, by discharge under erture in thechute 12. The chute 19 is also provided with a cover 20 which issupported by the brackets 21 in the manner described in connection withthe chute 12 and its cover 15. From the foregoingit will readily be seenthat the invention provides a novel and improved structure which permitsfree discharge of material from a bin regardless of the weight of thematerial overlying the discharge chute;

It will be understood that numerous changes and modifications and thefull use of equivalents may be resorted to without departing from thespirit 'or scope oft-he present invention as outlined in the append edclaims. 7

WVhat is claimed is: 1. The combination with a material bin and inclinedgravity discharge chute therein,

of means overlying said chute to prevent o pressure of said material toeffect movement of such material through said chute, said meansincluding a spaced cover for said chute, and brackets carried by saidchute for supporting said. cover.

2. The combination with a material bin and a substantially U-shapedinclined gravity discharge chute therein, of means overlying said chuteto prevent pressure of said material to effect movement of said materialthrough said chute, said means comprising a cover member supported bysaid chute and extending parallel thereto in spaced relation therefrom.

3. The combination with a material bin and a substantially U-shapedinclined gravity discharge chute therein, of means overlying said chuteto prevent pressure ofsaid material to efiiect movement of said materialthrough said chute, said means comprising a H flat cover member:supported by said chute and extending parallelthereto in spaced relationtherefrom. a

4. The combination with amaterial bin and a substantially U-shapedinclined gravity discharge chute therein,'oi means overlying said chuteto prevent pressure of said'material to effect movement 7 of said-mziterial through said chute, said means comprising a 7 flat coversupported by SLlCl'ChlllIG and eXtending parallel thereto in spacedrelation there from, and substantially U-shaped bracket members carried;by the sides of said chute and supporting said cover.
